Had a bizarre thing happen this morning. I opened the door and a loud hum started from the rear speakers. The radio wouldn't play although the display worked and it did this until I arrived at the office and until the power stopped about 5 minuted after locking the car. I later restarted the car and all is well. I'll talk to the dealer to see what's up but it was a bit spooky. Any thoughts?

My car did the exact same thing about a year ago. Only once. If I recall when I asked about it here, the concensus was something about the amp for the chime system was involved. I'll look later for the thread and see if I can find a link. It is pretty bizzare when it happens. ps: no codes were ever thrown and I'll have to check and see, but I'm pretty sure it was before my battery went kaput.
